n 30 Namd the a The press ram 16 is elevated by, the pull back cylinder 56 and their pistons 57 shown in the diagranunatic view Fig. 8.

The lpre-filler valve 9, located between the water supply tank (not shown) and the high pressure system, opens' downwardly and when steam is permitted t0 escape from beneath. the pull back pistons 57, the tendency toa vacuum created in the high pressure system, duc to the dropping of the ram 16, together with the pressure on the top of valve 9 from the Water in the supply tank with which pipe 15EL is connected, causes the valve 9 to open, thus permitting Water to enter the high pressure system and fill up the space caused by the dropping of the ram 16, Some air enters the lngh pressure pipes with the water and is objectionable as it makes an elastic cushion and causes a hammering or knocking similar to Water hammer in Water pipe systems. To overcome this l locate the valve 9 at the highest point, so that when the valve 9 is opened, the air escapes thus preventing any accumulation of air in the high pressure system. The valve 9 is opened to release the water in high pressure system, when it is necessary to raise the ram by the pull back pistons, by the lever 58, directly orindirectly engaging the outer end of valve stem 9a. This lever is connected by the jointed rod 59---59a with crank 60 on shaft 61, the latter being provided with a handle 62 by which it is operated.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is:-

l. The combination of a steam hydraulic intensifier, supply and exhaust steam valves for the intensifier, a floating lever, a rocking shaft carrying means for opening both of said valves, the said rockin shaft being connected with one end of the oating hand operated means connected with the other end of said lever, means connecting the steam piston and floating lever intermediate the ends of the latter whereby the floating lever will be moved by the said piston and speed reducing means forming a part of said connecting means whereby the speed and extent of movement of the Vfloating lever as compared with the speed and extent of movement of the steam piston is reduced. l

2. The combination of a steam hydraulic intensifier, 4supply and exhaust steam valves for the intensifier, a floatin lever, a rock ing shaft carrying a doub e crank, valve lifting arms carried by said double crank, means-connecting one end of said floating lever with the rocking shaft for rocking the latter, hand operated means connected with the other end of said floating lever, means connecting the steam piston and floating lever intermediate the ends of the latter lever,

whereby the position of the floating lever is changed by the movements of the piston and speed reducing means forming a part of said connecting means.

3. The combination of a steam hydraulic intensifier, supply and exhaust steam valves for the same, a floatingl'ever, a rock shaft, means connecting said shaft and one end of the floating lever whereby the movements of the lever are imparted to the shaft, two valve lifting arms carried by said rock shaft and actuated by the latter, the said arms having connection with the valve stems, means connecting the steam piston and floating lever whereby the latter has a movement with and in the direction of the piston, speed reducing means forming a part of said connecting means, and hand operated means also connected with said floating lever.

4. The combination of a steam hydraulic intensifier, supply and exhaust steam valves for the same, a floating lever, a rock shaft having crank connection with one end of said lever, hand operated means having connection with the other end of said lever, two valve lifting arms actuated by said rock shaft, whereby their inner ends are altern nately elevated and lowered by the rocking movement of the shaft, means loosely supporting the outer ends of the arms when the valves are closed and means connecting the steam piston and floating lever intermediate the ends of the latter for changing the position of the floating lever.

5. The combination'` of a steam hydraulic intensifier, supply and exhaust steam valves for the same, a floating lever, a rock shaft having crank connection with said lever, hand operated means also connected with said lever, valve lifting arms having indirect pivotal connections with said shaft whereby their adjacent ends will be lifted by the rocking movement of the shaft, means loosely supporting the outer ends of said arms, means connecting the piston and floating lever and speed reducing means forming a part of sald connecting means.

6. The combination of a steam hydraulic intensifier, supply and exhaust steam valves, valve actuating mechanism and means including speed reducing gears connecting the piston of the steam cylinder with the valve actuating means, whereby the latter are actuated by the movements of the steam piston.

7. The combination of a steam intensifier, supply and exhaust steam valves, valve actuating mea-ns, and means including rack bars and speed reducing gears connecting the rack bars for transm1tting movement from the'steam piston to the valve actuating means.
